Application filed April 11, 1913.. Serial 110,760,482. 1

To all whom it may concern Be it known that I, JOHN T. HAY, a citizen ofthe United States, residing at Union City, in the county of Randolph andState of Indiana, have invented certain new and useful Improvements in Journal Boxes, of which the following is a specification.

This invention relates to improvements in journal boxes for the shaftsor pins of connecting rods, pitmen, and the like, and the object is toprovide journal boxes ma plurality of parts of such a shape that thewearing surfaces will automatically ma1nta1n a good bearing fit against,the pin or shaft journaled in them, thus obviatmg the necessity ofremoval for refitting.

The object also is to provide a journal box in which the customaryjoint, between the two box members, permitting the escape of lubricatingoil, will be modified, and to provide means in conjunction with thismodified construction to retain the lubricant.

within the limits of the bearing surfaces of the journal.

The further object is to simplify and cheapen the construction ofjournal boxes without detracting from their utility.

I accomplish the objects of my invention by the mechanism illustrated inthe accompanying drawing, in which- Figure 1 is a view in side elevationof an end of a connecting rod containing my improvements, the crank pinbeing shown in cross section. Fig. 2 is a view in vertical sectionlongitudinally of the connecting rod through the flanged plates andflanged crank pin cutting off the flanges to expose the underlyingparts, and Fig. 3 is a cross section on the line 33 of Figs. 1 and 2.

Like characters of reference indicate like parts throughout the severalviews of the drawing. l

4 are the stems of a yoke secured to or forming part of the body of aconnecting rod or pitman, and 5 is a crossbar connecting the two stems.6 is a crank p1n passing be tween the stems 4. of the yoke. 7 is theouter bearing brass member and 8 is the inner bearing brass member, thevertical dimensions of which are equal to the diameter of the pin 6 sothat the planes of the upper and lower ends of these brass members aretangent to the periphery of the pin, as clearly shown in Fig. 2.

' 9 are filling plates between the pin 6 and the bearing brasses 7 and8, and the stems 4 annular flanges 15 having. two sides which are of theyoke. They have flangeslQ which overlap the stems 9'and the flangesll'which' overlap the bearing brasses 7 and 8, thus hold g the brassesin their proper positions relative to the stems 4;. Blocks 12 and 13enter between the flanges 11 and prevent the outward displacement of thebearlng brasses 7 and 8 from the pin 6. Shims 14 may be used if requiredbetween the blocks 12 and 13 and the bearing brasses 7' and 8 to take upany looseness due to wear or other causes.

The bearing brasses 7 and 8 fit between on the pin 6, and these flangeshave beveled inner faces, as shown in Fig. 3, to bear againstcorresponding faces of the bearing brasses 7 and 8 so as to make an oiltightfit between the bearing brasses and the flanges of the shaft or pinto prevent the escape and waste of lubricating oil at these joints. Asuitableopening 16 is provided through the top stem 4 and upper fillingplate 9 for the introduction of the lubricating oil into an oil cavity17 in the top of the bearing brasses.

While I have described my invention with more or less minuteness asregards details of construction and arrangement and as being embodied incertain precise forms, I do not desire to be limited thereto unduly orany more than is pointed out in the claims. On the contrary, Icontemplate all proper changes in form, construction and arrangement,the omission of immaterial elements and the substitution of equivalents,as circumstances may suggest or necessity render expedient.

I claim:

1. In a journal box for rotary shafts, a pair of bearing brasses eachhaving two sides which are substantially tangent to the cylindricalbearing surface of the shaft, all

of said sides being in parallel planes, shims contacting the bearingbrasses a connectingrod frame .within which the boxes are mountedfilling plates between'the bearing brasses and shaft and the frame,

plates having flanges to overlap the frame and flanges to overlap thebrasses and shims.

2. A journal box for a rotary shaft said shaft having a pair of annularflanges to receive bearing brasses between them, in combination with apair of bearing brasses each substantially tangent to the cylindricalbearing surface of the shaft, all of said sides being in parallel saidfilling planes, oil cavities in a plurality of said In witness whereof,I have hereunto set sides, a connecting-rod frame within which my handand seal at Union City, Indiana, 10 the boxes are mounted andfilling-plates bethis 3d day of April, A.
